In Marathon, some objectives require you to find hidden items before you can move in the game. One of these objectives is to find Key 18-452-136, which is needed to unlock a hidden stash in the Dormitories. The key is easy to miss because it is hidden in a small bunk area in one of the rooms. In this guide, we will show you how to get Key 18-452-136 in the Marathon.
How to Get Key 18-452-136
First, go to the hidden stash inside the Dormitories. When you interact with it, the game will tell you that you will need the Key 18-452-136 to unlock it. Go upstairs from the stash location. Once you reach the upper level, look for a room towards the back of the hallway.
Look for a door that has the number 18 on it. Open this door and step inside. When you enter, check the back wall of the room to find the numbers 1,2, and 3 on it. Inside the room, look for a bunk area. The key is hidden inside the bunk area. Search the bunk area carefully, and you will find the Keycard.
Once you have the key, go to the Dormitories and use the key to unlock the hidden stash. Now you can collect the Surveillance gear from the hidden stash in the Dormitories. You need to complete the whole objective in a single run without getting killed by the enemies.
After getting the Surveillance gear, place it in the Airfield and Flight Control area. After that, go to the North Orientation roadway checkpoint to activate the Surveillance equipment to complete the objective. You will earn 210 MIDA Reputation to complete the objective in a single run without getting killed and extracting safely.
